Summary:
- Astronomers have observed galaxies in the early universe "igniting" for the first time, marking the beginning of their formation and growth.
- These observations provide insights into the cosmic "baby boom" period, when the first galaxies were rapidly forming and shaping the universe as we know it today.
- The study of these early galaxy formations helps scientists understand the processes that led to the development of the large-scale structures and diversity of galaxies we see in the present-day universe.
